Who is actiself for?

When stress at work just won’t let up.

Chronic, high stress can lead to serious health problems such as burnout or even depression. Lack of exercise is an additional risk factor and also weighs on your mental health.

With a programme lasting several weeks, actiself helps you cope better with stress, move more and become more active. This way you can protect yourself from overload and prevent long-term health problems.

actiself supports you in these four areas:

Stress management

You learn to recognise stress early and counteract it in a targeted way, for example with short relaxation and breathing exercises. You also practise putting pressure at work into perspective and planning breaks deliberately. Step by step, you build routines that ease your everyday life.

Behavioural activation

Under stress, many people withdraw and do less and less. As a result, they miss exactly the experiences that bring joy and energy. With actiself, you deliberately plan pleasant and meaningful activities, including with other people, such as meeting friends. At the same time, you learn to cut back on things that are not good for you, for example too much screen time.

More movement in everyday life

Studies show that people who are physically active on a regular basis are less likely to develop depression, and that physical activity can reduce exhaustion, the core symptom of burnout. You don’t need to be an athlete: walks, cycling or taking the stairs all count. actiself helps you build lasting exercise routines into your everyday life. Your smartwatch or fitness tracker shows what you have already achieved.

Sleep hygiene

Good sleep is the foundation of recovery. You find out which habits support your sleep, from regular times to an evening routine, and try out small changes straight away.

How does actiself work?

One small step every day – supported by your smartwatch.

Effectiveness

Study shows: significantly fewer depressive symptoms.

around 30 %lower depression scores than the control group

In the SMART study at the Max Planck Institute of Psychiatry, the smartwatch-based intervention on which actiself is based was tested over 12 weeks.

The result: at the end, participants who received the intervention had significantly fewer depressive symptoms than the control group without the intervention – 9.8 instead of 13.9 points on the established PHQ-9 questionnaire.

Pilot study with 52 participants, published on medRxiv. A larger randomised study will follow as the next step.
